Private-line is a very popular transport method, ensuring throughput and reliability from point A to point Z. Private-line circuits can be delivered to a variety of end points, including a secondary location, a Central Office or a fiber hotel. Fiber hotel meet points are advantageous, minimizing the expense of a local loop.

Mammoth Metro Ethernet (MME) is a combination of multiple metro technologies onto a single platform. MME can be used for entrance or egress from Mammoth's network to an End User location, and spans across multiple local access providers. MME offers private-line transport within a LATA, and can be carried InterLATA on Mammoth's network to a second location or an aggregation point with Mammoth.

Mammoth Extended Reach Ethernet (MERE) utilizes legacy technologies like ATM, Frame Relay, SONET and TDM, which is converted to private Ethernet at a Mammoth hub location for construction of private-line where no Ethernet options exist. MERE services can be integrated into a private Layer 2 solution whether point-to-point, point-to-multipoint, or delivered to an aggregation point.

Mammoth Extended-Ethernet Transport (MEET) service provides Ethernet transport in a Metro area and InterLATA to a second location or to a Mammoth aggregation circuit. The MEET product line allows for the use of multiple high-cap formats to be cross-connected across Mammoth's private network. An example would be a TDM DS3 in one location cross-connected to a Metro Ethernet connection in another state. MEET product takes advantage of multiple routes and Mammoth's built-in redundancy to traverse the network from point A to point Z.
